Abstract

LA INVENCION ACTUAL PROPORCIONA (COMO SE PUEDE VER EN LA FIGURA) UN MECANISMO DE CONTROL DE UNA VALVULA ADECUADO PARA SU UTILIZACION EN UN TREN DE VALVULAS QUE TRANSMITE GANCHOS DESDE UNA LEVA (11) SITUADA EN UN ARBOL DE LEVAS (10) DE UN MOTOR DE COMBUSTION INTERNA HASTA UNA VALVULA DE CABEZA CILINDRICA (217) DEL MOTOR DE COMBUSTION INTERNA (11) Y UN ELEMENTO DE TOPE (212) EN UN TOPE CON LA LEVA (11) Y UN ELEMENTO DE TOPE SEGUNDO (215) EN UN TOPE CON LA PARTE SUPERIOR DEL TUBO DE LA VALVULA CILINDRICA (217). EL MECANISMO DE CONTROL DE LA VALVULA COMPRENDE UN ELEMENTO EMPUJA VALVULAS PRIMERO (213) QUE SE PUEDE DESLIZAR EN UN HUECO EN EL MOTOR, UN ELEMENTO EMPUJA VALVULAS (213) SEGUNDO QUE SE PUEDE MOVER EN RELACION CON EL ELEMENTO EMPUJA VALVULAS PRIMERO (212) Y UNOS MEDIOS DE BLOQUEO (220, 221, 222, 223) CAPACES DE BLOQUEAR LOS ELEMENTOS EMPUJA VALVULAS PRIMERO (212) Y SEGUNDO (213) PARA QUE SE MUEVAN EN CONJUNTO. CUANDO LOS MIEMBROS DE BLOQUEO (220, 221, 222, 223) PERMITEN QUE LOS MIEMBROSEMPUJA VALVULAS PRIMERO (212) Y SEGUNDO (213) SE MUEVAN EN RELACION ENTRE SI, AL MENOS UNA PARTE DEL GANCHO DE LA LEVA (11) PROVOCA EL MOVIMIENTO RELATIVO ENTRE EL LOS ELEMENTOS EMPUJA VALVULAS PRIMERO (212) Y SEGUNDO (213) MAS QUE CON EL GANCHO DE LA VALVULA CILINDRICA (217), POR LO QUE EL MECANISMO DE CONTROL DE VALVULAS REDUCE LA CANTIDAD DE GANCHOS QUE SE TRANSMITEN DESDE LA LEVA (11) HASTA LA VALVULA DE CABEZA CILINDRICA (217). EN LA PRIMERA DESCRIPCION DE LA INVENCION, EL MECANISMO DE CONTROL DE VALVULAS SE CARACTERIZA EN QUE UNO DE LOS ELEMENTOS EMPUJA VALVULAS (212, 213) SE PUEDE CONECTAR CON EL ARBOL DE LEVAS SOLO A TRAVES DEL OTRO ELEMENTO EMPUJA VALVULAS (212, 213). EN UNA SEGUNDA DESCRIPCION, LA INVENCION SE CARACTERIZA EN QUE LOS MIEMBROS DE BLOQUEO (220, 221, 222 Y 223) COMPRENDEN MEDIOS DE INCLINACION (222, 223) QUE APLICAN UNA INCLINACION PERMANENTE SOBRE LOS MEDIOS DE BLOQUEO (220, 221, 222, 223) QUE ACTUAN PARA INCLINAR LOS MEDIOS DE BLOQUEO (220, 221, 222, 223) EN UNA PRIMERA CONDICION DE FUNCIONAMIENTO EN LA QUE LOS MEDIOS DE BLOQUEO (220, 221, 222, 223) BLOQUEAN LOS ELEMENTOS EMPUJA VALVULAS PRIMERO (212) Y SEGUNDO (213) PARA QUE SE MUEVAN EN CONJUNTO.
